To all w kom it lmay .concern y Be it known that I, Josnrii Gr. KUHN'- rzlNeiin, a citizen ol the 'United States, and resident ot Chicago, in the county ot Cook and State of Illinois, have inreutell certain new and useful Improvements in Sectional Demountablc Rinis,of which `the following is a specification. y

. My inventionrelates to vehicle Wheels, and `more particularly to tire-receiviiigI means which are `employed for securing a. pneu matic tire upon the telly ot a motor vehicle fwheel. y

ipecifical;ly,iny invention has tor its oliject the provision olf means 'for quickly anrl effectively attaching and (letta-hing aV tire to or from its `carrying i'ini and upon the telly and rim ol a Wheel. This l. prefer to (lo by means ot' an aiinulus or ring thatl interlocks with a specially designed ltiro rini anti is locked oi" clampeclto the Wheel rim or telly `by the Wedge-clips usually employed in con `nection with a deinouiitable structure lor tires.

My invention is applicable to pneumatic tire-receivingw runs which are pcriiianently secured to the telly ol `thc wheel. as well as to tire-receiving riins tor `either clenclier beaded or straighosirlcfl pneumatic tire iasings. 4

The objects of iny invention are the pro `vision of a structure, sini-ple in arrangement and economical to manufacture, 'which can 'be operated by the unshilloil motorist in a minimurno'f time `and Without the bother now encountered. in changing casings upon `a rim and the changing.; ol rires upon the wheeh'Whichever in the particular.: casemay be necessary. It will, also ne secu from the following description anti accompanying.

' illustration that my invention may be einin Which-- ployecl in connection with either straight-V sided or clencher tires and with the ordinary wheels arranged for the receipt of demount `.able tires without any change in the tires or the Wheels as they are already malle and procurable upon the market.

I prefer to accomplish the above mentioned objects `by means of the instrumentalitiesillustrated .in the accompanying drawings,

Figure 1 is a fragmentary elevation of a ortion oit` the tire locking ring; yemployerl in mynew tire receiving rirn. i

Fig. 2 is a .fragmentary perspective ot' ay "typical form of wheel telly and telly bane Specication of Lettera Patent.

the style ol" rim in this vcase being `for the reception ot a clenchei' tire, although it will .be obvious that niy invention is applicable to rims for receiving' straight-sided tires or clenclier tires and lWhether therims be tixefl to the telly or (leniouiitable. i

In the drawings, similar reference characters are eniployeil to designate the saine 'pai w tl'ironghout the divers riewsancl by reference to Fig. 2 it will be seen that my tire receiving; Arini comprises a member torniecl to provide one llai'ige `5 and the looty:

toni l of a tire receiving' rini. Bottom 6 ex. tends to the placev of jnnctureof the de-N mountable flange. hereinafter to `be descrihcila and has extended from its eclge at s0 suitable intervals Hour, five 'or six, as may be (lesirerl) toiin'ues l., the outer portions 8 A ol? which are turned downward at right ano-les to bottoni (3, sufficient room being left between the erige of the' bot-tom and the g5 y rlownturneil portionS ol the tongue to receive the .detachable flange therebetween.

The detachable 'flange 9 is annular or ring 'shaped` and ot' suli'ficient Width to provide th necessary height to receive the edge of a tire 9o casing: anil to extenrl flownI upon the sident the telly* to the threaded stud 'l0 usually pro virletlfupon Wheels arrangetl to receive den'iountable'rinis for the receipt ol the Wedgeclip 1.1 usually employed. to `secure the. ilemountable rim upon. the wheel; At suitable intervals .the rletachableflange 9 has provided therein' crmcentric slots each having a,y restricted or narrow portion 120i such rliinensions as to receive'tlie shank portion of. 100

tongue 7 and joining therewith is a Wider'- portion 13` large enough to receive theheaders or downturned portion 8 of the tongue or the tapered Werlging portion 14 of Wedgeclip lil.

The manner oi.' assembling' this structure iis/as follows: The tire casing, with the tube therein. is piaceri upon the member constitutinp; flanges 5 and bottoni 6, and flange or or downturned portions 8 of the tongues extencl. through the enlarged portions 1301. the

` ring' .fl is their hrought that the headed 110 l tatedso as to cause the shank portions 7 of the tongues to enter narrow portions 12 of the slots in which position the flange is pre- Vvented from beingmoved laterally by the heads or ldownturned portions 8 of the tongues. The tire rim, and flange thus assembled may now be placed on the felly band of the wheel, if it has not already been .so placed, and the tapered portions 14 of the Wedge clips are introduced into enlarged portions 13 in the slots of flange 9 and between bottom 6 of the tire-receiving member and the felly band; wedge-clips 11 being secured in position in the usual manner by turning nuts 15 down upon the threaded studs 10 extending from the telly. For convenience in starting the flange when beginning to lisafcsemble the structure or in seating the structurey when finishing the assembly, l have provided flange ring 9 with embossments or teats 16 against which a screw-driver or chisel may be driven.

In Figs. 2 and 3 the felly body 17 is shown provided with a conventional form of telly band 1S, but in Fig. 4, I have shown the member constituting flange 5 and bottom 6 provided with oppositely extending flanges 19 and 20 for `liYedly securing this member to the fellyof a wheel; in such case the tongues 7 an'd downwardly bent ends 3 may be punched out of andv produced from a portion olE the flange 20. YWhere the tire-receiving rim is lixedly secured to the lelly wedge clips are not necessary and only. a single threaded bolt 21 is required to pass through the enlarged portion 13 of one of the slots for securing flange 9 in assembled position.

A1. A rim for receiving a tire formed of two circmnfcrentially extendin part-s provided with lug and slot connections that are engaged by relative circumferential movement of said members, and means enacting with the wheel. structure and entering the slot whereby the rim members are4 locked against reverse circumferential mmf'ement.

2. ln combination a wheel, a demountable rim thereon, the said rim formed of two circumferentiallly extending parts provided with lug and slot connections that are engaged by relative circumferential movement ot' the rim members. and means entering the slots whereby the rim members are locked against reverse circinnferential movement and the rim is secured to the wheel.

J'. The combination with the felly of` a wheel ol' a tire-receiving and holding structure detachably mounted thereon and comprising a flat rim body having a lateral flange along one edge, a substantially L- shaped lug projecting from the oppbsite edge ol' said rim body, a ring disposed la`1\ and having an the rim body to retain the' latter upon said 70 any.
